Helly Hansen Lifa Stripe Crew

Best for most people

The original synthetic base layer and the best seller among the branded ones here, made from polypropylene that moves sweat off your skin. It suits running, cycling and ski days where you work hard and need it to dry fast. Synthetic fabric holds smells more than merino, so it is less suited to several days of wear between washes.
